How to Use Transient View Objects to Store Session-level Global Variables
hi
Please consider section "40.8.5 How to Use Transient View Objects to Store Session-level Global Variables"
at http://download.oracle.com/docs/cd/E14571_01/web.1111/b31974/bcstatemgmt.htm#ADFFD19610
Based on this documentation I created the example application
at http://www.consideringred.com/files/oracle/2010/ProgrammaticalViewObjectAndRollbackApp-v0.01.zip
It behaves as show in the screencast at http://screencast.com/t/qDvSQCgpvYdd
Its Application Module has a Transient View Object instance "MyEmployeesContextVOVI", as master for the child View Object instance "EmpInCtxJobVI".
On rollback the Transient View Object instance keeps its row and attribute values.
Also when passivation and activation is forced (using jbo.ampool.doampooling=false ) the Transient View Object instance seems to keep its row and attribute values.
questions:
- (q1) Why does the expression #{bindings.MyEmployeesContextVOVIIterator.dataControl.transactionDirty} evaluate as true when a Transient View Object instance attribute value is changed (as shown in screencast at http://screencast.com/t/qDvSQCgpvYdd )?
- (q2) What would be a robust approach to make a Transient View Object instance more self-contained, and manage itself to have only one single row (per instance) at all times (and as such removing the dependency on the Application Module prepareSession() as documented in "5. Create an empty row in the view object when a new user begins using the application module.")?
many thanks
Jan Vervecken
Thanks for your reply Frank.
q1) Does sample 90 help ? http://blogs.oracle.com/smuenchadf/examples/
Yes, the sample from Steve Muench does help, "90. Avoiding Dirtying the ADF Model Transaction When Transient Attributes are Set [10.1.3] "
at http://blogs.oracle.com/smuenchadf/examples/#90
It does point out a difference in marking transactions dirty by different layers of the framework, "... When any attribute's value is changed through an ADFM binding, the ADFM-layer transaction is marked as dirty. ...".
This can be illustrate with a small change in the example application
at http://www.consideringred.com/files/oracle/2010/ProgrammaticalViewObjectAndRollbackApp-v0.02.zip
It now shows the result of both these expressions on the page ...
#{bindings.MyEmployeesContextVOVIIterator.dataControl.transactionDirty}
#{bindings.MyEmployeesContextVOVIIterator.dataControl.dataProvider.transaction.dirty}... where one can be true and the other false respectively.
See also the screencast at http://screencast.com/t/k8vgNqdKgD
Similar to the sample from Steve Muench, another modification to the example application introduces MyCustomADFBCDataControl
at http://www.consideringred.com/files/oracle/2010/ProgrammaticalViewObjectAndRollbackApp-v0.03.zip
public class MyCustomADFBCDataControl
extends JUApplication
@Override
public void setTransactionModified()
ApplicationModule vApplicationModule = (ApplicationModule)getDataProvider();
Transaction vTransaction = vApplicationModule.getTransaction();
if (vTransaction.isDirty())
super.setTransactionModified();
}Resulting in what seems to be more consistent/expected transaction (dirty) information,
see also the screencast at http://screencast.com/t/756yCs1L1
Any feedback on why the ADF Model layer is so eager to mark a transaction dirty is always welcome.
Currently, question (q2) remains.
regards
Jan

How to Create an Input Form using a Transient View Object?
I would like to use a Transient View Object to store data from input forms across a multiple-page enrollment process.
My question is how to I create the input form using the Transient View Object on the .jspx page? Do I drag/drop an ADF creation form onto the page? Or, use a regular ADF form? Do I need to create the initial row progammatically?
Just looking for some general directions or set of instructions? I've looked at the SRDemo example (Globals Transient View Object), but I'm not sure how they created the page at design time?
thanksWell following the SRDemo example, this seems to work:
1. Create Transient View Object
2. Add to Application Module as a Data control
3. Add to .jspx page as an ADF Form (not as an ADF Create Form)
4. Add following code to Application Module containting Transient VO instance:
protected void prepareSession(Session session) {
super.prepareSession(session);
insertTransientViewObjRows();
private void insertTransientViewObjRows() {
ViewObject transientvo = getViewObj1();
transientvo.clearCache();
transientvo.insertRow(transientvo.createRow());

How to retrieve the values from a Transient View Object
Hi Experts,
I am using Jdevelpoer11.1.1.5.0. I created one Transient view object with attributes EmpId,Salary.
In Backing Bean i will create rows for that view object and display it in the form of <af:Table> like Empid, Salary and an Update Link.
Now my problem is i want to update the salary of the particular EmpId. For Example if the EmpId is 100 and salary is 10000 now i want to increase the salary to 20000 and if i click on the update button; i want to retrieve the particular employee details in my backing bean. How can i acheive this?
Thanks in advance.A better approach would be to programmatically populate rows in the <VO>Impl.java by overriding the executeQueryForCollection(0 as specified here -
http://adfpractice-fedor.blogspot.in/2011/01/adf-bc-programmatically-populated-vo.html
You can write the logic to update the salary in an AM method then on click of Update or in the getter of Salry field if logic is valid for all fields... -
How to access a view object under a nested appmodule in servlet
Hi,
Can anyone tell me how to access a view object under a nested appmodule in a servlet?
I know that I can use
ApplicationModule app = Configuration.createRootApplicationModule(amDef, config);
ViewObject vo = app.findViewObject(viewObjectName);
to get hold of an appmodule and view object.
But in a nested appmodule, for example, I have am0 as root, am1 as child, and voZ within am1, what should I use for this amDef? config? and viewObjectName?
Your help would be much appreciated.Hi,

Filtering Transient view objects
Guys,
I have transient view object.
i have populated the rows programatically.
Based on some UI action, i need to filter the rows in the view object. Whenever i filter the rows (using view criteria), i can't get back the lost rows again.
For eg.. i have populated the view object with 5 rows.
Based on View criteria(VC1), i got only 2 rows.
Now i need to apply the same view criteria(VC1) with different values for bind variables, but it applies the criteria on the remaining 2 rows. (but am expecting to apply the criteria on the actual 5 rows)
I think transient view object is loosing rows on applying view criteria.
How this can be solved?Hi,
can you try using rowmatch
refer following method inside viewobjectimpl
public void matchByCustomerNumber(String custno) {
RowMatch rm = new RowMatch("CustNumber = " + custno);
setRowMatch(rm);
setQueryMode(ViewObject.QUERY_MODE_SCAN_VIEW_ROWS | ViewObject.QUERY_MODE_SCAN_DATABASE_TABLES);
setSortBy("CfMonth DESC");
executeQuery();
}you should also see other query modes.
ViewObject
look for QUERY_MODE_SCAN.. contants.

Insert data into multiple entities at once using a view object
Hi,
I'm trying to insert data into multiple entities at once using a view object, but unfortunately it doesn't seem to work. The two entities have a 1:1 association. I created a view object which contains both entities and I made sure they aren't read-only. But like I said it doesn't work, I can't insert data in both entities at once... :(
Is this possible? And how (if it is)?Hi,

Is this possible? And how (if it is)? Peter:
This is definitely supported and tested. Please send us the exception stack trace. You must running into other problems. A few things to note:
A) You have to mark the entities as both updateable (not read-only) and not reference-only.
B) If you're not seeing an exception stack, turn on diagnostic. Here is how:
To turn on diagnostic, go to the IDE,
1. Select the project.
2. Do right mouse click and select "Project Settings..."
3. On the Settings dialog, select Configurations/Runner.
4. In the righthand side pane, you should see a textbox for "Java
Options". Please add the following JVM switch:
-Djbo.debugoutput=console
Then, rerun. The run command should include
-Djbo.debugoutput=console as in
"D:\JDev9i\jdk\bin\javaw.exe" -Djbo.debugoutput=console -classpath ...
You should now see a lot more output on the IDE's message window. Here you should see the exception stack trace.
If you invoking your app directly from command prompt, just add "-Djbo.debugoutput=console" after your "java.exe".
Thanks.

Using a view-object as a data web bean?
Hi,
When writing JSP pages, I'd like to have a web bean that allows basic data manipulation such as:
- set up a row set - e.g. by specifying a view object and an (optional) where clause;
- navigate this row set (first, next, etc.);
- get or set the values of the attributes of the current row;
- insert, update or delete a row;
- commit or rollback the modifications;
- etc.
This bean should be "silent" - i.e. it would not have to be able to "render" anything - instead, I would use it in <%= bean.method() %> tags, or in <% ...java code... %> sections, in conjunction with other (custom) beans.
I guess I could use a view object - but:
1) How would I have to use it in a JSP context?
2) Or, are there more appropriate objects to do this job?
3) What methods could I use (i.e. where are they documented)?
4) What pitfalls should I be aware of (most notably related to housekeeping after bean use)?
Any information greatly appreciated!
Thanks in advance,

Using SQL view object to create ADF table
Hi,
I have created a column called "Month" (which extracts month from the date column) and another column to count the no. of requests.
i want to create an ADF table with 2 columns, a column showing the month and another is showing the no. of requests for that month.
However, now I only managed to achieve the ADF table to show the overall total requests, which means if i add up all the requests for all the months and i get 500
My ADF table shows this:
Jan: 500
Feb: 500
Mar: 500
How should I create the view or what should I do to make it such that the no. of request is based on the month?
Please advice.
Thanks (:Hi,
For the given situation you can create a Query Based View Object with the following query
SELECT
COUNT(TEMP1.DT) REQUEST,
TO_CHAR(TEMP1.DT, 'Mon') MONTH
FROM
TEMP1
GROUP BY
TO_CHAR(TEMP1.DT, 'Mon')
where DT is the date column and temp1 is the name of the database table.
Following are the steps that i followed to get this query :
i have taken the following sample table :
create table temp1
(srno number primary key,
dt date)
*Note you may use any existing column instead of srno or use dt only (i took an extra column as u know we need a primary key /row id)
the following is the sample data
insert into temp1 values (1,sysdate);
insert into temp1 values (2,sysdate);
insert into temp1 values (3,add_months(sysdate,1));
insert into temp1 values (4,add_months(sysdate,1));
insert into temp1 values (5,add_months(sysdate,3));
insert into temp1 values (6,add_months(sysdate,5));
the table appears as follows
SRNO DT
1 22-JUN-12
2 22-JUN-12
3 22-JUL-12
4 22-JUL-12
5 22-SEP-12
6 22-NOV-12
To start with ADF View Object Creation (Using Jdeveloper 11.1.2):
Create the view object using Create View Object wizard
In Step 1. Name window
set the value for Name : Viewab (you can use any of ur choice)
In the data source section : select query
In Step 2. Query window
a. Click Query builder (it will pop up sql statment window)
b. In the SQL Statement window
in quick-pick objects section -> select temp1 table -> shuttle the columns from available list to selected list
in select clause section -> select srno column from select list-> choose count() function from function drop down list -> insert function -> set alias to REQUEST-> click validate
now select dt column from select list -> choose to_char() function -> click insert function -> alter the function to to_Char(temp1.DT,'Mon') -> set alias to Month -> click validate
in the group by clause section -> Click the green symbol to add -> from the expression palette insert dt column -> insert the to_char function -> alter the function to to_char(temp1.DT,'Mon') -> click validate
in the Entire SQL Query section -> click test query -> in the test query window -> click query result-> you will see the result -> click close -> click ok
Click next
Step 3: Bind Variables
Click Next
Step 4: Attribute Mappings
click Finish
So the view object is ready :) -
Okay so I set up my Time Capsule already and is now backing up 2 of my iMacs. Works great. What I want to know is how to use the TC to directly store files? I want to do this to delete some files on iMac 20inch but still have them on the TC for future reference..eg some movies on iTunes. I want to directly save them on the drive so I can delete them from iTunes and gain some storage. (Ps on iMac 20 inch (it's almost full - 320 GB) when I enter time machine, a tab comes up on finder which reads "Time Machine backups" it's able to be ejected like a disc or a connected device. On the iMac 20 inch, I dragged some files onto there as if using it like a hard drive. Is this the correct method? Then I went to my 27inch iMac and saw the "Time Machine Backups" hoping to see the files I dragged from the 20inch iMac. But the files were not there except a folder that said "Backups.backupdb". Can someone help me?
It's not a good idea to use a network disk for both Time Machine backups and other things. By design Time Machine will eventually consume all the space on its output disk, which will then cause problem for your other files. I'd store those other files on an external disk connected to the Time Capsule. The problem with that is that Time Machine will only back up files that are local to your Mac. That means that you'll only have one copy of the files on or attached to your Time Capsule.

How to get the view Object in UserDefined Action
Hi All,
Any body tell me how to get the view object , like the view object avilable in the wdDoModifyView() method as parameter.
I have requirement like, i want to change the , no of rows displaying in the table should be changed at the runtime based onthe no of rows selected in the dropdown box.
The action which i created will be assigned to that dropdown box, on select of the available option, i will get the view object and change the properties of the "maxrows" of the table .
so for getting the view object in the the Action methods tell me what is the procedure for getting the current view object.Hello Vishal,
Simply create a value attribute (say rowCount) of type 'integer' and bind it to the 'visibleRowCount' property of your table. Then, in the actionHandler get the value from the UI element (in your case, I guess it is drop down) and set it to the attribute 'rowCount' like this.
wdContext.currentContextElement.setRowCount(
wdContext.current<nodeElement>.set<AttributeBound toDropDown>);

How to create a view object and attach with extended AM
Hi,
I tried to create new vo and attach this vo with the extended AM. But it is throwing error like 'PC.NAME : invalid identifier' (Actually this PC.NAME is exiting one).
Now i want to know how to create a view object similar like seeded one but with one additional condition in the where clause.
It is possible though extension, but i want to create two view object similar like seeded one, one with some other condition in the where clause
and another one with some other condition.
So for my requirement, i'll extend one VO and i'll add my condition but how to do it for second condition.
But i want same seeded VO with two different condition.
Any suggestions please,
SANSAN,
There is no need to attach the newly created VO with extended AM. You need to attach the same with the standard AM.

Error in using Dynamic View Object
Hi
I am doing a experiment to create dynamic VO and using it.
Experiment details:
I want to create dynamic VO and dynamic message choice and associate the dynamic VO to dynamicaly cretaed message choice.
code scriplet
In AM
public void dynamicVO()
OADBTransactionImpl txn =(OADBTransactionImpl) this.getTransaction();
OAViewDef viewDef = txn.createViewDef();
// viewDef.addEntityDerivedAttrDef();
viewDef.setSql("select EmpEO.EMPNO, EmpEO.ENAME, EmpEO.JOB, EmpEO.DEPTNO from EMP EmpEO");
viewDef.setExpertMode(true);
viewDef.addEntityUsage("EmpEO","va.oracle.apps.fnd.experiment.server.EmpEO",false);
viewDef.setViewObjectClass("oracle.apps.fnd.framework.server.OAViewObjectImpl");
viewDef.setViewRowClass("oracle.apps.fnd.framework.server.OAViewRowImpl");

What is the use for lock object and how to use the lock objects
Hi Guru's,
I am new to ABAP .Can you please clarify the that what is the use of lock object and how to use the loct object .what is use of the Deque & Enque function modules .hi ,
below are some minfo about lock objects :
Lock Objects
These types of objects are used for locking the access to database records in table. This mechanism is used to enforce data integrity that is two users cannot update the same data at the same time. With lock objects you can lock table-field or whole table.
In a system where many users can access the same data, it becomes necessary to control the access to the data. In R/3 system this access control is built-in on database tables. Developers can also lock objects over table records.
To lock an object you need to call standard functions, which are automatically generated while defining the lock object in ABAP/4 dictionary. This locking system is independent of the locking mechanism used by the R/3 system. This mechanism also defines LUW i.e. Logical Unit of Work. Whenever an object is locked, either by in built locking mechanism or by function modules, it creates corresponding entry in global system table i.e. table is locked. The system automatically releases the lock at the end of transaction. The LUW starts when a lock entry is created in the system table and ends when the lock is released.
Creating Lock Objects
Lock object is an aggregated dictionary object and can be defined by using the following steps:
o From initial data dictionary screen, enter the name for the object, Click Lock object radiobutton and then click on Create. The system displays a dialog box for Maintain Lock Objects screen
o Enter short text as usual and the name for primary table.
-Save
-Select Tables option
From this screen you can:
Select secondary tables, if any, linked by foreign key relationship.
Fields for the lock objects. This option allows you to select fields for objects (R/3 system allows locking up to record level). Lock object argument are not selected by user but are imposed by the system and includes all the primary keys for the table.
1) Exclusive lock: The locked data can only be displayed or edited by a single user. A request for another exclusive lock or for a shared lock is rejected.
2) Shared lock: More than one user can access the locked data at the same time in display mode. A request for another shared lock is accepted, even if it comes from another user. An exclusive lock is rejected.
3) Exclusive but not cumulative: Exclusive locks can be requested several times from the same transaction and are processed successively. In contrast, exclusive but not cumulative locks can be called only once from the same transaction. All other lock requests are rejected.
Also, last but not the least, locking the object is logical (locking with any enqueue ) .so, you have to use the lock object while trying to access from second program .
reward if helpful ,

Ranjita
